A day before intercourse, have your woman eat a roll of pennies. The next day, begin intercourse when your woman feels the bowel movement coming. When your about to nut, have your woman stand on a chair over you and release her bowels, showering you in a deluge of shit and change.
Last night Betty and I performed the most epic Obama Landslide. She released so much change, I couldn't even tell how shitty it was.
